I've been made aware that some people might want to buy one of these for their own gun, so I've decided to offer them for sale.

The compensator is machined from 6082 T6 /HE30 general engineering grade aluminium bar, with cutouts to fit the Cyma/Cybergun and TM Thompson M1A1 without modifying the foresight.Finish options are painted matt black or unfinished, raw metal. The matt black matches my Cyma/Cybergun M1A1. I don't have access to a TM version, so I can't work out a paint match.There are no "trades", etc. on it.

Not yet. I don't have access to one, and I've not even seen one in person. Mine are Cyma/Cyberguns.I've also not heard from anyone who's bought one if theirs is TM. The one sent for fit-testing on a TM was unpainted.
